31. Sin Offering of Officiating Priest—The sins of the people were transferred in figure to the officiating priest, who was a mediator for the people. The priest could not himself become an offering for sin, and make an atonement with his life, for he was also a sinner. Therefore, instead of suffering death himself, he killed a lamb without blemish; the penalty of sin was transferred to the innocent beast, which thus became his immediate substitute, and typified the perfect offering of Jesus Christ. Through the blood of this victim, man looked forward by faith to the blood of Christ which would atone for the sins of the world (The Signs of the Times, March 14, 1878).
